摘要
十二烷基苯磺酸(简称DBSA)掺杂聚苯胺形成离子性聚苯胺(简称PADB).以乳化聚合所得的产物PADB因含有过量的DBSA.在清洗前后,发现(极子/双极子)转移的最大吸收波长并不一样.丙酮清洗PADB前后的λmax分别为775nm及878nm.过量的长链烷基化合物对PADB的伸展是不利的,因而降低电导率数,当PSS(聚苯乙烯磺酸)的量低于10%,发现(极子/双极子)转移的最大吸收波长为红移,当PSS的量高于10%时则为蓝移.
Mixing polyanline,Dodecylbenzenesulfonate（referred DBSA）form ion-doped polyaniline polyaniline（referred PADB）.In emulsion polymerization resulting product PADB because it contains an excessive amount of DBSA.Before and after cleaning,we found（pole/di-pole）maximum absorption wavelength shift is not the same.Acetoneλmax PADB were around 775 and 878nm.Excess of the long-chain alkyl compound is disadvantageous for PADB stretch,thereby reducing the degree of conductivity,when the amount of PSS（Polystyrene sulfonate）is less than 10%,we find（pole/di-pole）transfer of the maximum absorption wavelength red shift,blue shift when the amount was higher than 10% PSS.
